Protein should make up about 10% to 35% of your total daily calories. If you have kidney problems, you may need less. Ask your doctor about that and follow their advice. Choose lean meats, poultry, fish, beans, nuts, or low-fat dairy products.
Some food packages list “net carbs,” “impact carbohydrate,” or “digestible carbohydrate,” but the FDA hasn't defined those terms. If you have diabetes, don't rely on them, since you could misjudge how a food affects your blood sugar. Focus instead on a food’s “Total Carbohydrate.” You should have carbs as 45 to 65 percent of your daily diet.
